To all whom it may concern:

Be it known that I, LAWREN on E. KELLEY, a citizen of the United States,residing at- Leonard, in the county of Fannin and State of Texas, haveinvented a new and useful Cultivator, of which the following is aspecification.

The present invention relates to improvements in cultivators, one objectof the pres ent invention being the provision of an adjustable couplingto be used in combination with the tooth supporting beam and frame ofthe cultivator so that the said beam may be positioned at any desiredangle for projecting and maintaining the teeth at the necessary anglefor removing or throwing the earth to and from the plants.

lVith the foregoing and other objects in View which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed can be made within thescope of what is claimed without depart ing from the spirit of theinvention.

In the drawings Figure 1 is a side elevation of the coupling in operablerelation to the frame and the tooth carrying beam of the cultivator.Fig. 2 is a rear elevation thereof without the tooth carrying beam. Fig.3 is a top plan view of the coupling as shown in Fig. 2. Fig. 4 is afront elevation of the present coupling. Fig. 5 is a section taken online 5-5 of Fig. 2 showing a portion of the tooth carrying beam.

Referring to the drawings, the numeral 1 designates the tooth carryingbeam, which is provided with two spaced apertured lugs 2.2, which aredisposed to receive the thimbles 8-3 of the supporting lugs 1-4l, of themain carrying plate 5 of the present coupling. A tie or pivotingybolt 6is provided and properly secures the beam 1 to the plate 5. This plate 5is made in the form of a channel plate so as to be properly reinforcedand has attached to the front face thereof adjacent the upper end, theblock 7, which is provided with the screw threaded aperture for thereception of the feed and adjusting screw 8, which as clearly shown isrotatably mounted in the sleeve 9 carried by the horizontally disposedadjusting plate 12, the same being provided with the lower re duced andapertured lug 10 for the reception of the pivoting support 11, which connects the lug or projecting portion 10 to the lower end of thesupporting plate By this means it will be seen that the screw 8 willpermit of the swinging movement of theplate 12, so that the same mayassume various angles, as indicated in dotted lines Fig. 1, the dottedlines indicating the position of the center of the plate 12, when invarious positions. If so desired, the support of the screw feeding block7 may be pivotally connected to the plate 5, and thus permit of thenecessary swinging or flexing of the plate or member 12, which carriesthe clamping plate 13 which with the bolt 14 properly secures thepresent device to the supporting beam 15.

In order to assist in steadying the plate 12 when in proper adjustedposition, the apertured lug 16 is connected to the rear face thereof andis disposed to receive a bracing member (not shown).

From the foregoing description, it is evident that. when it is desiredto tilt the beam 1 and consequently the apertured lugs 2-2 so as topresent the tooth carrying beam at any desired angle, that the screw 8is 1'0- tated and when coacting with the feeding block 7 will cause theplate 12 to be moved with the fastening device 11., and as the same canbe moved to either side, the beam 1 may be tilted to either side and atthe necessary angle for presenting the cultivator teeth or shovels (notshown), either for directing the earth to or from the plants as may befound necessary.

What is claimed is:

1. The combination with the frame of a cultivator and a tooth carryingbeam, of a coupling therebetween, consisting of a member attached to thetooth carrying beam, at second member attached to the frame of thecultivator, and cooperable means carried by both members for adjustingsuch members relative to each other to regulate the angle of dispositionof the tooth carrying beam, said coacting means including a pivotalconnection for one member to the other, and a feed screw carried by onemember for adjustably engaging the other member, at a point remote fromthe pivotal connection.

2. The combination with a cultivator frame and a tooth carrying beamthereof, of a coupling therebetween, including a plate connected to thebeam, a feed screw carrying block carried by the plate, a feed screwmounted therein, a clamping member for engaging the frame of thecultivator, means for connecting the same to the screw, and a pivotalconnection between the latter member and the plate.

The combination with the frame of a cultivator, and a tooth carryingbeam thereof, of means for attachingthe beam ad justably to the frame ofthecultivator, including a vertical plate, provided with two spacedlugs, means for attaching the lugs to the tooth carrying beam, a blockattached to the plate near one end thereof, a feed screw mounted in saidblock, a clamping plate attached to the frame of the cultivator andcarrying the feed screw, and means for pivotally connecting the clampingplate to the opposite end of the first plate.

4. The combination with the frame of a cultivator, and a tooth carryingbeam, of a coupling therebetween, including a plate connected to thebeam by a lateral swinging hinge, aclamping plate attached to the frameof the cultivator and pivotally con nected to one end of said firstplate, and cooperable means carried by the other end connected to thebeam by a lateral swinging hinge, a clamping plate attached to the frameof the cultivator and pivotally connected to one end of said firstplate, 00-

operable means carried by the other end of said clamping plate andthe'first plate for adjustably connecting the clamping plate thereto,said latter means including two" spaced sleeves carried by the clampingplate, a feed screw rotatably mounted therein, and ablock provided witha threaded aperture therethrough carried by the first plate and fittingupon the screw.

In testimony that I claim the foregoing as my own, I have hereto afiiXedmy signature in the presence of two witnesses.
